Freelancer profile translated to English.

Description

Hello, I'm Junior, a junior developer passionate about code and creation. I enjoy transforming an idea into a concrete project, whether it's a strategy game developed with Unity and C# or a small application to test new technologies.

I'm also keenly interested in artificial intelligence and blockchain, which I explore out of curiosity and a desire to anticipate the uses of tomorrow.

What motivates me is learning by building. Each project is an opportunity for me to progress, find creative solutions, and bring real value to those I collaborate with.

If you're looking for someone serious, curious, and involved, but also approachable and motivated, I'd be delighted to discuss your projects.

API Security & Backend Developer
September 2025 - January 2026 (4 months)
Tunis, Tunisia
Full Stack Developer with a Security Focus | .NET API · Flutter · DevSecOps
I am a Full Stack Developer with a genuine interest in cybersecurity and secure application design, working on real-world projects that bring together software development, infrastructure, and application security.
On the backend side, I have designed and deployed a production-ready API using ASP.NET Core 8 on a Linux VPS running Ubuntu. The architecture follows industry best practices: Nginx as a reverse proxy, HTTPS enforced through Let’s Encrypt, and service isolation managed with systemd. This hands-on experience has given me a solid foundation in backend security, deployment workflows, and Linux system administration.
In parallel, I develop mobile applications with Flutter, with a consistent focus on secure client-server communication — covering API protection, token lifecycle management, and data security on the device itself — while maintaining a clean and responsive user experience.
My approach to development is DevSecOps-oriented. I integrate security at every stage of the build, drawing on JWT authentication, role-based access control, CORS policies, and OWASP best practices to protect against common threats such as injection attacks and XSS vulnerabilities.
Technically, I work with ASP.NET Core (.NET 8) on the backend, Flutter for Android on the mobile side, and manage infrastructure through Linux, Nginx, and systemd. I use Git and Postman as part of my daily workflow.
What I bring to a project is the ability to build secure, scalable APIs, develop mobile applications connected to backend systems, conduct basic security reviews for web and mobile applications, and handle production deployments with a security-first mindset.
I am particularly drawn to opportunities in Application Security, API Security, and DevSecOps — areas where good engineering and security thinking go hand in hand.
